If I had any scrap plastic I'd give it a go, but the only discs I could dye are already dark colors. When you say "actual methodic experiment" do you mean having a few different baths with the same concentration of dye and the main difference being a pH of 3, 5, and 7?

So Rit is thee dye, but has anyone found a better dye? One with less fade/bleeding? I have heard Metal Complex dye, as well as fast milling dye might work better on polyurethane than rit. Any experimenters out there?
